I To all whom t may concern:

, at Rendebanen 1, Kolding, county of Ribe,

Kingdom of Denmark, have invented certain new and useful Improvements inMachines for Cleaning Separator-Disks, of which the following is aspecification.

As is Well known, the proper cleaning of the skimming disks of thebowl-inset in centrifugal cream separato-rs is a very troublesomeprocess, since the dirt in the milk is deposited on the disks in hardcakes, or crusts, which can only be removed with difliculty by means ofstrong and long-contin-v ued -brushing after previous soaking in dilutedsoda-lye. For cleaning these disks, common, stiff brushes have hithertobeen used, but they were not practical, and therefore t-he presentinventlon refers to a machine which in few minutes can clean a largenumber of skimming-disks. i

My invention is set forth in the accompanying drawings, in which- Figure1 :is a sid-e View of the machine; Fig. 2 shows the inner brushdetached; and Fig. 3 is the guidespndle for the inner brush.

The machine consists of a @shaped frame 1', which forms a bearing forthe main shaft 24, carrying a pulley 11. On the shaft 24 is a collar 12outside of the frame, and on said shaft, Within the frame, is a nicalcog-Wheel 2 in mesh With a pinion 3son the shaft 16, which runs in Athebearings25 and 26. On the shaft 1G there is also disposed a cog-Wheel 4,which meshes with another cog-wheel 27 on the shaft 28 running in thebearings 29 and 30. On this shaft there is also disposed asprocket-wheelffl, on which a chain not shown in the drawing transmitsthe motive power to another sprocket-wheel 5 on the outer end of thehollow shaft 6. This shaft, which4 runs in the bearing 26, surrounds theinner shaft 16 and bears, on its outermost end, a number of lateral arms7 providing supports for the brush-wings 8 which are secured by vbolts32 in such a Way that they can be adjusted at different angles by meansof set-A screws 33 in the brackets 13. On the end of the inner shaft 16there is a finger or fork 9, and a screw 10 to which the guide-spindle18 (Fig. 3) may be secured.

' On the guide-spindle 18 there may be disposed a tube 20 with handle 23and finger, orV

fork, 21. On this tube are disposed a number of oblique, brush-carryingarms 22 which may be adjusted t'o different angles. The adjusting meansshown consists of bracketarms 19 that receive screws 22 on thebrush-carrying arms 22, there being wing nuts 22b to move said screwsaxially and thus vary the angle of said arms 22.

The machine operates in the following manner; to fit1-The pulley 11turns the shaft 24, whose motion is transmitted to the shaft 16, Whichturns in one direction, transmitting motive power to the linger, lorfork,9, while the brush-wings 8 are turned in the opposite direction bymeans of the gears 4 and 27, shaft .28 and sprockets 31 and 5. Askimming disk from a centrifugal cream separator is now vplaced looselyover the finger, or fork 21, and the tube 20 is passed over theguide-spindle 18 until the fingers, or forks, 21 are grasped lby thefingers 9, when the brushes 22 will turn in a direction opposite to thatof the brushes 8, while the disk remains still between the two sets ofbrushes, as the brushes revolve in opposite directions with equal speed.As soon as the disk is cleaned, the tube 20 is removed from theguide-spindle 18, and a new disk is put in place. In this manner thecleaning of each disk only takes as many seconds as the old method tookminutes.

Itis obvious that t-he different parts of the machine may be varied inmany different Ways Without deviating from the principle of theinvention.

Having now described my invention .what I claim as new and desire tosecure by Letters Patentis:

1. A machine for cleaning the skimming disks of centrifugal creamseparators, comprising two shafts one within the other. means forturning the shafts in opposite directions, two sets of adjustablebrush-carrying arms between 1which the disks are wheel on the innershaft in mesh with a gear Wheel on the said intermediate shalt to drivethe latter, and a chain and sprocket wheel connection between the saidintermediate shaft and the said outer shaft.

3. ln a machine for cleaning the skimming disks of centrifugal creamseparators, inner and outer sets of arms carrying brushes between whichthe disks are adapted to be placed, supports on which the outerbrush-carrying arms are adjustably mounted, brackets on the said arms,and set screws carried by said brackets for adjusting the said outerbrush-carrying arms to diti'erent angles according to the shape of thedisks.

4. in a machine for cleaning the skimming,f disks of centrifugal creamseparators, inner and outer sets of brushes between which the disks areadapted to be placed, the inner set of brushes comprising a number ofoblique brush-carrying arms, a tube on which the arms are disposed,bracket arms, screws on the brush-carrying arms and engaging saidbracket arms, and means for moving the screws in said bracket arms toadjust the said brush-carrying arms.

5. A machine of the character described, comprising inner and outer setsof radially adjustable brush-carrying arms, means or rotating the innerand outer arms in opposite directions, one set of arms being removablymounted.

6. lin a machine of the character described an outer brush-carrying arm,means for adjusting said arm laterally, an inner brushcarrying arm,means for adjusting the inner arm laterally', and means for rotating theinner and outer arms in opposite directions.

7. ln a machine or" the character described, a frame, a spindle on saidframe, a brushcarrying member fitting said spindle, revolving meanssupported on said trame independently ot' the spindle, and means on thesaid brushcarrying member to detachably engage with the said revolvingmeans.

8. er machine of the character described, comprising a trame, a spindleon said trame, a brush-carrying member iitting said spindle, revolvingmeans supported on said frame independently of the spindle, means on thesaid brush-carrying member to detachably engage with the said revolvingmeans, a series of lateral arms supported to rotate on the 'frame aroundthe anis of the said spindle, means for rotating said arms, andbrush-carrying means supported on said arms.

9. A machine oi the character described, comprising a frame, outerbrush-carrying means, means for rotating said outer brushcarrying means,a member revolubly mounted on the frame, inner brush carrying means anda coacting member on said inner brush-carrying means, to engage saidrevolubly mounted member.
